Ikamva leiimodulators ze-electro optical
Ii-electro optic modulators zidlala indima ephambili kwiinkqubo zanamhlanje ze-optoelectronic, zidlala indima ebalulekileyo kwiindawo ezininzi ukusuka kunxibelelwano ukuya kwi-quantum computing ngokulawula iipropati zokukhanya. Eli phepha lixoxa ngemeko yangoku, impumelelo yamva nje kunye nophuhliso lwexesha elizayo lwetekhnoloji ye-electro optic modulator.
Umfanekiso 1: Uthelekiso lokusebenza kweentlobo ezahlukeneyoi-modulator yokukhanyaubuchwepheshe, kuquka i-thin film lithium niobate (TFLN), ii-III-V electrical absorption modulators (EAM), ii-silicon-based kunye nee-polymer modulators ngokubhekiselele ekulahlekeni kokufakwa, i-bandwidth, ukusetyenziswa kwamandla, ubungakanani, kunye namandla okuvelisa.
Iimodulators ze-electro optic zemveli ezisekelwe kwi-silicon kunye nemida yazo
Iimodulators zokukhanya ze-photoelectric ezisekelwe kwi-silicon bezisisiseko seenkqubo zonxibelelwano lwe-optical kangangeminyaka emininzi. Ngokusekelwe kwisiphumo sokusasazwa kwe-plasma, ezi zixhobo zenze inkqubela phambili emangalisayo kwiminyaka engama-25 edlulileyo, zonyusa amazinga okudluliselwa kwedatha ngama-odolo amathathu obukhulu. Iimodulators zanamhlanje ezisekelwe kwi-silicon zinokufikelela kwi-4-level pulse amplitude modulation (PAM4) ukuya kuthi ga kwi-224 Gb/s, kwaye nangaphezulu kwe-300 Gb/s nge-PAM8 modulation.
Nangona kunjalo, ii-modulators ezisekelwe kwi-silicon zijongene nemida esisiseko evela kwiimpawu zezinto. Xa ii-transceivers ze-optical zifuna amazinga e-baud angaphezu kwama-200+ Gbaud, i-bandwidth yezi zixhobo kunzima ukuhlangabezana nemfuno. Olu daba luvela kwiimpawu ze-silicon - ibhalansi yokuphepha ukulahleka kokukhanya okugqithisileyo ngelixa ukugcina ukuhanjiswa okwaneleyo kudala ukutshintshiselana okungenakuphepheka.
Itekhnoloji yemodyuli esakhasayo kunye nezixhobo
Ukunqongophala kwee-modulators zemveli ezisekelwe kwi-silicon kuye kwakhokelela uphando kwizixhobo ezizezinye kunye nobuchwepheshe bokudibanisa. I-Thin film lithium niobate iye yaba yenye yamaqonga athembisayo kwisizukulwana esitsha see-modulators.Iimodyuli ze-electro-optic zefilimu encinci ye-lithium niobateilifa iimpawu ezibalaseleyo ze-bulk lithium niobate, kuquka: ifestile ebanzi ecacileyo, i-electro-optic coefficient enkulu (r33 = 31 pm/V) iseli ethe tye i-Kerrs effect inokusebenza kwiindidi ezininzi ze-wavelength
Inkqubela phambili yakutshanje kwitekhnoloji ye-thin film lithium niobate ivelise iziphumo ezimangalisayo, kuquka i-modulator esebenza kwi-260 Gbaud enezinga ledatha le-1.96 Tb/s ngetshaneli nganye. Eli qonga linezibonelelo ezikhethekileyo ezifana ne-CMOS-compatible drive voltage kunye ne-3-dB bandwidth ye-100 GHz.
Usetyenziso lwetekhnoloji entsha
Uphuhliso lwee-electro optic modulators lunxulumene kakhulu nezicelo ezintsha kwiindawo ezininzi. Kwicandelo le-artificial intelligence kunye namaziko edatha,ii-modulators ezikhawulezayozibalulekile kwisizukulwana esilandelayo sonxibelelwano, kwaye usetyenziso lwe-AI computing luqhuba imfuno yee-transceivers ze-800G kunye ne-1.6T ezixhunywayo. Itekhnoloji yeModulator ikwasetyenziswa kwi: ukucubungula ulwazi lwe-quantum i-neuromorphic computing I-frequency modulated continuous wave (FMCW) itekhnoloji ye-lidar microwave photon
Ngokukodwa, ii-modulators ze-thin film lithium niobate electro-optic zibonisa amandla kwiinjini zokucubungula i-optical computation, zibonelela nge-modulation ekhawulezayo yamandla aphantsi ekhawulezisa ukufunda koomatshini kunye nezicelo zobukrelekrele bokwenziwa. Ezi modulators zinokusebenza nakwiiqondo lobushushu eziphantsi kwaye zifanelekile kwii-interfaces ze-quantum-classical kwimigca ye-superconducting.
Uphuhliso lwee-electro optic modulators zesizukulwana esilandelayo lujongene nemingeni emininzi emikhulu: Ixabiso lemveliso kunye nobukhulu: ii-thin-film lithium niobate modulators okwangoku zinqunyelwe kwimveliso ye-wafer ye-150 mm, nto leyo ebangela iindleko eziphezulu. Eli shishini kufuneka landise ubungakanani be-wafer ngelixa ligcina ukufana kwefilimu kunye nomgangatho. Ukudibanisa kunye noyilo oludibeneyo: Uphuhliso oluphumelelayo lweii-modulators ezisebenza kakuhleifuna izakhono ezibanzi zoyilo oludibeneyo, ezibandakanya intsebenziswano yabayili be-optoelectronics kunye nabayili beetship ze-elektroniki, ababoneleli be-EDA, ii-founts, kunye neengcali zokupakisha. Ubunzima bokuvelisa: Nangona iinkqubo ze-optoelectronics ezisekelwe kwi-silicon zinganzima kangako kune-electronics ze-CMOS eziphambili, ukufikelela ekusebenzeni okuzinzileyo kunye nesivuno kufuna ubuchule obukhulu kunye nokuphuculwa kwenkqubo yokuvelisa.
Iqhutywa kukukhula kwe-AI kunye nezinto zezopolitiko, eli candelo lifumana utyalo-mali olongezelelekileyo koorhulumente, kumashishini nakwicandelo labucala kwihlabathi liphela, nto leyo edala amathuba amatsha entsebenziswano phakathi kwezemfundo kunye noshishino kwaye ithembisa ukukhawulezisa ukwenziwa kwezinto ezintsha.
